RE: st: Comparing datasets
Thank you! By preceding the code with
-version 9-
then the program written by Tim Wade works just fine.

Sorry Rajesh, I don't know what is meant by putting v9 on top of the
do file! Michael
Hi,
Did you try putting version 9 on top of the do file and running it? it did
not work for me on version 9 when I ran it as is. However, it did when I
put
version 9 on top of the do file.

I haven't been following this thread, but in the past I had troubles
after running statements like:
tempfile t1
save `t1', replace
Technical support told me that "replace" should not be used when
saving temporary files.

I'm not sure what the problem is, I tested this example in Stata 9.2,
and it seems to work there, as does this improved example based on
posts by David and Eva:
sysuse auto.dta, clear
tempfile auto
save "`auto'", replace
clear
sysuse auto.dta, clear
drop make
tempfile auto2
save "`auto2'", replace
clear
desc using "`auto'", varlist
local x `r(varlist)'
desc using "`auto2'", varlist
local x2 `r(varlist)'
local diff2: list x - x2
di "`diff2'"

Hi Tim,
Is your example for Stata 10? When I try to reproduce your nifty
example, I
get:
. save "`auto2'", replace
invalid file specification
r(198);
Michael
There is probably a more elegant solution to this, but saving the
variable names in a local macro and comparing the macro lists might
work, e.g., :
. sysuse auto.dta, clear
(1978 Automobile Data)
. preserve
. drop make
. tempfile auto2
. save "`auto2'", replace
file C:\DOCUME~1\twade\LOCALS~1\Temp\ST_00000005.tmp saved
. restore
.
. local x
. foreach var of varlist _all {
2. local x "`x' " "`var'"
3. }
. di "`x'"
make price mpg rep78 headroom trunk weight length turn displacement
gear_ratio foreign
.
. clear
. use `auto2'
(1978 Automobile Data)
.
. local x2
. foreach var of varlist _all {
2. local x2 "`x2' " "`var'"
3. }
.
.
. local diff2: list x - x2
. di "`diff2'"
make
.
end of do-file
. Hope this helps, TIm

Robert,
The problem with cf2 & cf3 is that, they compare the variable
VALUES.
I intend to append the data and just want to ensure that the
variable
NAMES match and not the variable values.
At present -append- offers no way to check this.

Raphael,
Check out the compare cf2 and cf3 commands. The latter two
can be
found on the SSC archive.
